I mean the game is designed for fans of DnD, that is why they got the rights to make BG3 and call it DnD. If they change the DnD 5e ruleset for one, it will piss off the very fanbase the game is designed for. For two, it could potentially piss off WotC who own DnD and could yank any future DnD titles.
This game is designed for a specific audience.
Why you even think something so selfish? Every developer tries to sell their game for as many people as possible. Especially with big and expensive title. Not for some specific community.
How is that selfish? Every game has a target audience. FPS games are obviously aimed (haha pun intended) at those who enjoy FPS games. Do you go play COD and whine about there being guns in the game or having to shoot people?
Fighting games are aimed at competitive gamers primarily; they balance and design their games for those gamers.
Sim style games are aimed at those who enjoy simulations--ie, flight sim. You wouldn't go to flight sim and whine because it's too realistic, would you?
Historical games are aimed at history buffs. Would you go to the Kingdom Come: Deliverance website and cry that the combat is too realistic?
Racing games are aimed at those who enjoy racing. Would you go play Grand Turismo and cry about the fact that there are cars in the game?
And yet, when I point out that BG3 is aimed towards those that enjoy DUNGEONS AND DRAGONS, I am the selfish one? How about those crying about the core mechanics are the selfish ones, demanding the game studio change core mechanics that theydon't like, when the majority of the playerbase the game was DESIGNED FOR, like the mechanic they are whining about?
Tell me again how it is selfish to want to keep the game mechanics what A, was advertised, and B, is what the target audience enjoys?
